Find the 14th term of the geometric sequence 9, 18, 36
diamong [38]

Answer:

9 × 2^(13)

Step-by-step explanation:

hello :

the nth term is :  An =A1 × r^(n-1)

a common ratio is : r  and  A1 the first term

in this exercice :   r= -3-(-7)36/18 = 18/9 =2         A1 = 9

when : n =14 you have the  14rd term  A14

A14 = 9 × 2^(14-1)  = 9 × 2^(13)

What is the lcm of 18 and 30 using prime factorization?
Nuetrik [128]

18 = 2×3×3

30 = 2×3×5

The LCM will have factors of 2, 3², and 5. (Choose the highest power of each prime.)

2×3×3×5 = 90 is the LCM of 18 and 30.

Use a scientific calculator or unit circle to convert the polar form of the complex number to its equivalent rectangular form.
GuDViN [60]
I assume 3.14 is meant to represent π. So x=32cos(π/3)=16 and y=32sin(π/3)=16√3=27.7128 approx.
If we take 3.14 directly (radians), then we get x=16.0147 and y=27.7043 approx.
